Abstract
The microwave transmission between wave guide regions (a, b) having different internal gas pressures and/or different fill-gas compositions, that is to say, the coupling or outcoupling of microwaves of such a wave guide region into another region is improved in that between the wave guide regions at least a single pumping stage (6, 7, 8, 9) is inserted. The wave guide (1) is connected to the pumping stages preferably via the slots (2, 3, 4, 5) which do not virtually outcouple the microwave power.
